Balancing current within a parallel modular converter system

Abstract:

A current balancing system, and associated method and computer-readable medium are disclosed herein. The current balancing system comprises a plurality of power inverters, each power inverter included within a respective current loop and configured to generate a corresponding current amount. The current balancing system further comprises a plurality of inverter controllers, each inverter controller associated with a respective one of the plurality of power inverters and configured to receive a reference frame-transformed amount of the corresponding current amount. Each inverter controller is capable of independently controlling the corresponding current amount provided to a load.
